To @ZZ whom it may concern:

Be it known that I, ANTOINE SIRET, residing at Roubaix, in theDepartment of Nord, France, have invented certain new and use fulImprovements in Looms for IVeaving Tufted Fabrics, of which thefollowing is a specification. v

This invention is the subject of the following Letters Patent in foreigncountries: France, No. 178,612, dated September 18, 1886; Belgium, No.74,713, dated October 2,1886; Great Britain, No.12,543, dated October 2,1886, and Germany, No. 42,835, dated October 15, 1886. This inventionrelates to looms for weaving pile carpets of the Smyrna kind and othersimilar pile fabrics, wherein the woolen or pile warps are tied aroundthe ground warps, producing a pile of the Smyrna kind. In its generalconstruction the loom comprises a series of bobbins, upon which theground warpthreads are wound, said bobbins being journaled in carrierswhich are mounted in and between two vertically and independentlymovable beams, to which the bobbin-carriers are removably attached, sothat the bobbins may be held in place alternately by each beam, in orderthat the pile warp-threads may be passed both above and beneath thebobbins. The pile warpthreads are each wound upon a spool-roller orbobbin, all of the said spools being mounted upon a rotary drum, bymeans of which they are brought into action as desired. The pilewarp-threads are tied around the ground warpthreads, and after being sotied the weft-threads are shot in the usual manner, and are then beatenup. The several mechanisms for effecting these operations are allactuated by a series of hooked rods, which are brought into engagementin the proper sequence with a single verticallyreciprocating beam, whichis in turn actuated by a treadle.

The loom is illustrated in the accompanying drawings, in which- Figure 1is a vertical longitudinal section of the loom. Fig. 1a is a detail viewof part of the mechanism shown in Fig. 1. Fig. 2 is a verticalcross-section of the loom. Figs. 3 ande are side views, looking,respectively, at

opposite sides of the loom. Fig. 5 is a detailed cross-section, on anenlarged scale, of the bobbin-carrying beams, showing the relation ofthe bobbins thereto. Fig. 6 is a longitudinal vertical section through asmall portion of the bobbin-carrying beams, showing one of the bobbinsand its carrier in section. Fig. 7 is a plan view of one end of theupper bobbin carrying beam, showing its guides in section. Figs. 8, 9,and 10 are de- 6o tail views showing the means for retaining the ends ofthe pile warp-threads in place. Fig. 10 is a face View of a fragment ofthe pile-warp drum, showing the position of one of the pile-warp rollersand of one of the warp guide slats or rods thereon. Fig. 11 is a detailfragmentary view of the batten-teeth. Fig.

Figs. 7o 13,14, and 15 are detailed views of the hook ends of the actuating-rods,showing the several constructions thereof. Fig. 16 is a detail view ofclutch mechanism for giving the proper tension to the pile warp-threads.7 5 Figs. 17 to 28, inclusive, are detail views, partly diagrammatic,showing the various positions of the principal parts which effect theformation of the pile and which correspond to the various phases of thework. Fig. 29 8o shows in plan the formation of the pile. Figs.

30 and 31 show in section and plan, respectively, a diagram of a Smyrnapile fabric as produced by the loom.

Referring to the first four figures, A is the frame-work of the loom,and B is the vertically reciprocating beam extending transversel yacross the frame-work, which actuates the various mechanisms and whichslides in vertical slots a i'n the frame-work. This 9: beam is weightedby weights b, so that it descends by its own weight, and it is raised byconnection with a treadle O, suit-ably journaled to the frame-work. `Thebeam is pivotally suspended by pivoted links c from lever-arms d,rigidly'secured to a rock-shaft D, and the treadle is connected by apivoted rod e to a lever-arm E, also rigidly secured to the samerock-shaft.

For convenience in describing the loom the roo treadle end of the loomwill be considered the front.

F F are the two bobbiii-carrying` beams, extending` transversely acrossthe loom beneath and parallel with the operating-beam B. Said beams F Fare movable, vertically sliding on suitable guides on the frame-work.Then the loom is at rest, the lower beam F is supported in its uppermostposition by pivio oted links j" j", the lower ends of which are held inslotted lever-arms f which are rigidly secured to a rock-shaft G,journaled in the frame-work beneath and parallel with the bobbin-beams,as best shown in Figs. l and 2. rlhevertical reciprocation of thelowerbeam F is effected by the rocking of the shaft G, and said shaft isrocked by the operating beam B, with which it is connected by means offour hooked rods 2, and t, the hooks 2o of which are at the proper timesprojected across the path of the operating-beam, but of these four rodsthree-1, 2, and Al-are ordinarily held out of co-operat-ion therewith bysprings g g. 'lhree of these rods-wiz., l, 2, and t-have their hookedends shaped, as shown in Fig. lt, so that when they engage theoperating-beam they embrace the same,whe1'eby said rods are affectedbythe movement of the beam in either direction, and the fourth 3o hook 3has its hooked end shaped like that shown in Fig. 13, so that it iseffected only by the upward movement of the operating-beam. 'lhe rods l,2, and are all connected to the rock-shaft at one end of the same, asshown in Figs. 2 and t. The rods l and 2 are pivotally connected to theouter end of a downwardly-extending crank-arm 71 secured to therock-shaft, and bot-h extend upwardly toward the operating-beam B, theirupper hooked 4o ends being' held, when theloom is at rest, just in therear of the path of the beam, and opposite its lowest position, suchbeing the position shown in Fig. -l-. The rod 3 is pivotally connectedat its lower end tothe outer end of i 5 an upwardly-extendingcrank-arm7U, secured to the rock-shaft G diametrieally opposite to the arm 71.This rod passes in front of the operating-beam, audits upper hooked endis normally held in t-he plane of the path of the oper- 5o ating-beam,but above the upward limit ofthe movement thereof. The rods 2 and 3 arenear their central parts bent toward each other, and they are held atall times in contact with each other by the spring g of the rod 3. Owingtothe location of the arms 7L 7l. on the shaft G, when the rods l and 2are raised the rod 3 will be depressed, and when the rod 2 is swungforward to bring its hook into connection with beam B the rod 3 will beswung 6o away from the beam, and its hook will thus be carried beyondthe pla-ne of the path of the beam. rlhe fourth rod is pivotallyconnected at the other side of the frame-work (sec Fig. 3) to adownwardly-extending crankarm 712 on the opposite end of the rock-shaftG, said arm being parallel with the arm 71, to which the rods l and 2are connected. This rod extends behind the beam l?, and has its hookedend arranged in the same manner as these of the rods l and 2. If, then,any one of the rods l, 2, or 4 is swung forward at the proper time whenthe beam B is at its lowest position, thehooked end of such rod willcmbrace said beam, and the movement then of the beam will rock theshaftGbaek and forth, depressing the bobbin-beam F when the beam l israised, and raisin g the bobbin-bcam when the operating-beam is lowered,as will be evident from an examination of Figs. l, 2, and 4; but if therod 2l, when in its lewermost posi,- tion, has its hooked end projectedacross the path of the beam, so that its hook is engaged by the beam,said rod will only be affected by the upward movement of said beam, (oiing to the shape of its hooked end, shown in Fig. 13,) and such. upwardmovement would cause the shaft G to be rocked in the direction to raisethe bobbin -beam F to its normal position.

The movement of the rods il, 2,and l across the path of theopcrating-beam is effected by the following mechanism: In the rear ofsaid rods is journaled, crosswise of the framework, a rotary shaft Il',carrying a ratchet wheel i. (1o-operating with this ratehet-wheel is apawlj, pivoted toa link w, which is hung at one end upon the shaft ll,and the other end of this link is pivotally suspended by a rod 7;. froma lever-arm 7 on the main iockshaft D; hence each rocking of the shaft Drotates the shaft ll a certa-in uniform distance. As will appearhereinafter, a complete sequence of operations in the weaving iseffected by eight depressions of the treadle, and hence the parts are soproportioned that the shaft ll will be rotated one-eighth of a completerotation at each rockin g of the shaft D. To insure the shaft Il beingheld in the proper place at each movement, it carries au octagonal diskm, against the periphery of which presses a spring-actuated bar ln. Theshaft ll carries a series of drums I, located at proper intervals, andon the periphcries of these drums are fixed tappet-pins o, one for eachof the rods l, 2, and 4.-, as well as for other rods, to be referred tohereinafter. These tappet-pins al'e so located that at the proper momentcach will be brought in contact with its rod to swing the same acrossthe path of the opei'atingbeani, and when said tappet-pins are movedaway from their rods the rods will be returned to their normal positionsby their respective springs y.

The upper bobbin-carrying beam. F' normally occupies its lowermestposition when the loom is at rest, and it is held in this position byrestin g on the bobbin-earriers, which are in t-urn supported by thelower beam F. This beam F is lowered by means of its own weight, and israised by means of two pairs of hooked rods 5 5 and G G, pivotallyconnected, one of each pair, at opposite ends of the beam. These rodshave hooks like those shown in Fig. 13, and when the rods are at restthese TOO IIO

hooks are in the rear of the lowermost position of the beam B,being heldaway from the same by springs (7. In proper order one of these pairs ofrods is swung across the path of the beam by two of the tappet-pins 0,so that when the beam B ascends the bobbinbeam F is also raised. Whenthe rods 5 5 are thus engaged by the beam B,the bobbinbeam drops on thedescent of the beam B; but when the rods 6 6 are engaged' by theoperating-beam and are elevated thereby they are held elevated bypivoted springlevers 7 7, having catches p p on their lower ends, whichengage notches q q in the rods 6 6. Vhen the beam B then descends, thedownward movement-of the bobbin-beam F will not be affected, and itremains elevated until other tappet-pins o strike the upper ends of thecatch-levers 7 7 and move their catches out of engagement with the rods6 6. The bobbin-beam then descends of its own weight. The bobbin-beammay thus be raised, lowered, and held in its upper as well as in itslower position.

Referring vnow to Figs. 5, 6, and 7, J J are narrow metal bobbins uponwhich the ground warp-threads X are wound. These bobbins are mounted inannular bobbin-carriers K K, in which they are retained by studs r fr onthe carriers which enter between the cheeks of the bobbins. The outgoingend of each ground warp-thread passes out through an eye in one of thestuds r and another guideeye s on the bobbin-carrier. These bobbins andtheir respective carriers supply the ground warp-threads, and areconsequently equal in number to that of these threads. Eachbobbin-carrier terminates at top and bottom in projecting feet t t,which enter in slots in the upper and lower bobbin-beams F F, wherebythe bobbin-carriers are held and guided in place. Since the lower feetof the bobbin-carriers rest in and are held by the lower bobbin-beam,the carriers will be held in place thereby when the upper bobbin-beam israised, so that the upperbobbin-beam may be raised clear above the upperfeet of the vcarriers to enable the pile warp-threads to be passed overand between the bobbins. It is also essential for the weaving of thefabric, as will appear hereinafter, that the pile warpthreads should bepassed beneath some or all of the bobbins and their carriers, and toenable this to be done it is necessary either that the bobbin-carriersshould be lifted with the upper bobbin-beam, or should be supportedthereby when the lower bobbin-beam is depressed. To this end the upperend of the upper foot t of each bobbin-carrier has a notch u cuttherein, which, when the loom is at rest, is above the upper surface ofthe upper bobbin-beam. The notches on adjacent bobbin-carriers arearranged on opposite sides of the feet t, so that the notches alternate.The notches on both sides are engaged and disengaged by sliding serratedbars LL, which are mounted on the upper bobbin-beam, so as to be movedto and from the bobbin-carrier feet t. These sliding bars are connectedwith leverarms o o, which are secured to rock-shafts M M, journaled inbrackets on the bobbin-beam. These rock-shafts are actuated byhookedrods 8 9, which are pivotally connected with lever-` arms w w on therock-shafts M M. The upper ends of these rods have hooked ends of thecharacter shown in Fig. 13, and they are arranged to be swung intocooperation with the operating-beam B by means of the tappets o o in thesame manner as the hooked rods yalready described, and they are heldnormally out of co-operative position. b y springs g in the manneralready described. The relative position of these rods 8 and 9 is shownin Fig. 2. Vhen in their normal position, when the loom is at rest, thesliding bars L L are out of engagement with the bobbin-carriers, andthey are brought into engagement therewith only when the rods 8 and 9are acted upon bythe tappet-pins. It only one rod 8 is acted upon, onlyone half of the bobbins will be affected thereby, and the otheralternate half will be affected by the action of the other rod, whereasif both rods are acted upon simultaneously all the bobbins will beaffected. When the bobbins an d their carriers are thus engaged, if thelower bobbin-beam is depressed the bobbins will beheld suspended fromthe upper bobbin-beam, and if when so engaged the upper bobbin-beam israised the bobbins will be raised therewith.

The ground warp-threads pass forward over a roller N in the front of theloom and thence to the cloth-beam O. Between. the bobbins an d theroller N the ground warp-threads pass between the teeth 0c of theswinging hatten P. The hatten is pivotally suspended from a rock-shaftQ, mounted in the upper part of the frame. The batten is arranged so asto be shifted laterally a distance equal to double the distance betweentwo of the warp-threads. This is effected by mechanism shown in Figs. 2and 4. The shaft Q carries a cam y, of sufiicient size and shape tocause the hatten to move the proper distance, and this cam bearsLagainst a part of the batten frame. The shaft is rocked by means oflever .c and rod 2', which connect it with a hooked rod l0, to which therod z is pivoted. This rod l0 has its end hooked in the manner shown inFig, 13, and is brought into (3o-operation with the operating-beam B(away from which it is normally held by spring g) by one of thetappetpins o.

The woolen or pile warp-threads are all carried by a rotatingdrum R,journaled in the frame-work behind the bobbin-beams. This drum carriesnear its periphery and entirely around the saine a series of rotatingbobbins or rollers S S, which are journaled in opposite ends of thedrum, and which extend crosswise of the loom. Only afew of these rollersare shown in the drawings, but it will be understood that they will bearranged around the entire periphery of the drum.

There is a IOO IIO

pile warp-threml Y for each point of the surface of the fabric to beproduced, and the pile warp-threads to form a series or row of pointsclear across the fabric are all wound upon a single roller S. XVhen oneline of points has been woven in, the drum is then rotated to bring thenext pile-thread roller into position, and so on. For obtaining designsin weaving, care must be taken to ar 1ange the threads of differentcolors upon each roller and upon the several rollers on the drum, so asto be only obliged to apply successively to the several rollers toobtain from each the lengths of thread for one line of points of thefabric, and to produce automatically by this means the desired design.The drum thus provided with the separate rollers permits of theproduction of designs on pile fabrics without the use of Jacquardapparatus.

rl`he drum is turned, after the formation of cach line of points, eitherdirectly by hand or, preferably, by being provided with a gearwheel D,which engages with a worm-gear o. on a shaft h', operated by ahand-wheel c. The drum is held stationary during the work by means of aspring-actuated bar l1', which bears against a four-sided disk c on theshaft b.

Thepropertenson is given to the pile warpthreads Y during the formationof the points by the clutch mechanism coacting with the pile-wa rproller S in operation, which is shown in Figs. 4 and lfhFig. 1Gbeingafragmcntary vertical cross-section through the periphery of thedrum. The sliding and rotary clutch memberg is adapted to engage the endof each roller S in turn, and it is brought into engagement therewith bymeans of a crank-handle fi. and shaft j', which is connected with thesliding clutch member by crank-arm 7s and lever l. As shown in Fig. lO,the pile-warp rollers S are, for the sake of compactness, staggered, andhence two clutching devices are necessary.

The proper tension is given to the clutch members by weights m', whichare connected to cords n', which pass over pulleys o', and wind uponspools p on the clutch-shafts. Then t-he clutch members are out ofengagement with the pile-warp rollers, they are held from being turnedby the weights m by the `grip of the lever Z.

In order to apply tension to the particular roller S, in operation thecrank-handle i', Fig. i, is turned so as to rotate shafty" in thedirection indicated bythe arrowin Fig. 1G, thus moving crank-arm 1 inthe same direction. This movement of the crank-arm oscillates the leverl', thus sliding the clutch member g toward and into engagement with theend of roller S. The weight m then acts upon the spoolp, exerting aforce in the proper direction to give tension to the pile warp-threadson the roller S.

O11 the periphery of the drum, extending crosswise of the same, equal innumber and parallel with the roller S, are a series of slats or rods T,(sec Fig. 10%) over which the pile warp-threads Y pass in being carriedto the ground warp-threads, whereby the pile warpthreads are properlyguided and directed.

The tying' of the pile warp-threads to the ground warp-threads isaccomplished (scc Figs. SO and 3l) by carrying the ends of the pilewarp-threads over the ground-warp bobbins to a point between the bobbinsand the roller N, the pile warl'i-threads bein g equal in number to theground warp-threads. lVitb their ends held above the ground warp, eachpile warp-thread is then placed beneath one of the ground warp-threads,then over two ground warp-threads, and then down around one thread, andthence up, where the other end of the pile warp-thread isleft free.These general operations, which will hereinafter be more specificallyset forth, it is seen consist of forward, upand-down, and lateralmovements of the pile warp-threads, which nievements areeffectedbymechanisms, as follows:

lleld in position in braeketsvq on the periphery of the drum R, andimmediately in front of the guide-ba1"l`, is apile-warp-carrying bar U,the ends of which project on cach side beyond the drum. (See Figs. 8, 9,and lO.) To this bar U the ends of the pile-threads are nipped by anipping-rod 1", Iiournaled on the bar U. In front ofl this nipping-rodis a groove s', over which the ends of the pile warp-threzuls areplaced, and along which a knife is passed to render the ends of thethreads uniform. This pile-carrying bar is free to be moved forward awayfrom the drum toward the roller N.

Pivoted to one side of the frame at t (see Fig. 3) is a sway-beam V,which at its rear end is pivotally connected to a crank-arm u on arockshaft lV. Secured to this shaft lV on opposite ends of the drum R(see Figs. 3 and t) are two oscillating arms A', to the upper ends ofwhich are pivotally connected cam-shaped sliding arms I3', having forkedends fc', which rest on guide-rollers fw immediately in the rear of theprojeetin g ends of the pile-carrying bar U.

In front of the pivotal point t of the swaybcam a hooked rod lll ispivoted thereto. This rod has a hooked end of the character shown inFig. 13, and it coacts with the main operating-beam B in the same mannerand is actuated by the same mechanism as the hooked rods alreadydescribed. lVhen this ITO rod ll. is raised by the beam B, the slidingarms ll are moved forward, taking up the pile-bar U and carrying itforward and downward to the point :r (see Fig. l) above the groundwarp-threads imniediately behind the roller N. The bar U remains in thisposition during the subsequentweaving, being held in position in, theforked ends of the arms B by the tension of the pile warp-threads, andis then retracted bythe lever y and rod y2, acting upon the sway beam V.(See Fig. 3.) The pile-bar U is carried forward in front of thegroum'l-warp bobbins at a time when the upper bobbin-beam F is raisedabove the bobbin-carriers, so that the pile-bar passes above thebobbin-carriers and beneath the upper bobbin-beam. The pile-bar is alsocarried forward in front of the hatten and above the hatten-teeth,passing between the suspension-bars of the hatten-tooth bar. Vhen thepilebar is carried to its extreme forward position, where it rests onthe ground-warp, the pile-warp threads are located between thehatten-teeth, as indicated in Fig; 1. rlhe movement of the pile-bar U inthe proper path is determined by the curved or camshape of the slidingarms B. These arms move in the spaces between the upper and lowerbobbin-beams at the ends of the same which are not filled with thebobbins, as shown in Fig. 2.

The vertical movements of the pile warpthreads are effected by means ofa vertieallymovable thread-shifting frame O, located between the drum Rand the bobbin-beams F F. This pile-thread-shifting frame, which is bestshown in Fig. 2, consists of two rectangular slides a2 at opposite sidesof the loom, which slide vertically in the framework, and these twoslides are connected by two rods b2, extending crosswise of the loom.The rectangular slides are on their inner sides cut away to formopenings c2, which constitute continuations of the space d2 between therods b2. Vhen the pile-bar U is carried forward, it passes through thespace d2 and openings c2, the sliding levers B passing through thespaces formed by the rectangular slides, Figs. 1 and 2. Accordingly,when the pile-bar is carried forward to the point 9c', the pilewarp-threads Y are between the two rods h2, and any vertical movement ofthe shifting-frame C thus would cause the portions of the pilewarp-threadsbetween the ground-warp bobbins and the drum R to be movedup or down. The shifting-frame C is suspended at its opposite ends bycords or straps e2, which pass over pulleys f2, and to which areattached weights D', which normally hold the frame when the loom is atrest in its most elevated position, being the position shown in Fig. 1.In this position the space d2 between the rods h2 is in line with thepile-bar U when held in operative position on t-he drum, and also withthe upper ends of the bobbin-carriers.

The shifting-frame C', when lowered, is automatically raised by theweights D', and it is lowered by the following mechanism: Be-v neath theshifting-frame C and journaled in the main frame-work A is a rotaryshaft E', carrying near its opposite ends two drums or disks g2, to eachof which is secured ythe end of a strap i2, the other end of which issecured to the frame C. When the shaft E is rotated in the direction ofthe arrow in Fig. 4, the shifting-straps are wound upon the drums, thusdepressing the frame. This shaft is connected to be thus rotated todepress the shifting-frame C nin two ways, either when the mainoperating-bar B is depressed or when it is raised. Referring to Figs. 2and 3, 7'2 is a disk or drum 'secured to the extreme 'right of the shaftE', and to this is attached one end of a strap k2, which is partly woundaround the disk or drum, so that when the strap is pulled it will rotatethe shaft. The other end of this strap is secured to the lower end of ahooked rod 12, which passes through a guide-bracket Z2, the rod having astop 'm2, coacting with said bracket to hold the rod in normal position.The hooked end of this rod is shaped as in Fig. 13, and it is normallyheld out of and is brought into co-operation with the beam B in the samemanner as the hooked rods already described, so that when in eooperationwith the beam B the elevation thereof will lift the rod and rotate theshaft E.

Referring now to Figs. 2 and et, n2 is a grooved pulley secured to theextreme left end of the shaft E. Secured to and partly wound upon saidgrooved pulley is a cord o2, which passes upward around pulleys p2 p2 tothe highest part of the loom, and thence downward, where its other endis attached to a hooked rod 13, which itself constitutes a weight tohold the cord taut. This rod 13 slides freely in a vertical directionthrough a guide-bracket r2. The hooked end of this rod is shaped asshown in Fig. 15, being different from the previously-described hookedrods, and having a different action, not being acted upon by a spring orby a tappet-pin. Normally, when the loom is at rest, the hooked rod 13is held elevated above and out of reach of the main beam B. The cord o2winds upon its grooved pulley n2 in the same direction that the strap7a2 winds on the drum J2, so that when the beam B, on being raised,unwinds the strap 7a2 the cord 02 is also partly. unwound. The unwindingof the cord 02 allows the rod 13 to drop until it occupies the positionshown in Fig. 4that is, with its hook just below and in the path of thebeam B. When now the beam descends, it comes in contact with the rod 13,still further depressing the same, and so still further lowering theshifting-frame Cf.

The diagrams Figs. 17, 18, and 2O show the three positions to which theshifting-frame C may be moved.

The lateral movements of the pile warpthreads are effected by thehatten, the operation of which has already been described, and also bylongitudinally-sliding combs G G2, mounted on the lower and upperbobbin- `beams, respectively, on their sides next the drum R. The pilewarp-threads are brought IOO IIO

into engagement with these combs by the vertical movements of theshifting-frame C. The mechanism for shifting these combs laterally isbest seen in Fig. 12. Each comb is mounted on its beam by slots s2 andpins t2, so as to permit of Vtheir sliding, and each is connected by apivoted link u2 to one arm of a bell-crank lever H pivoted to the beam,which is heldin either position toV which it is moved by a spring ri. Onits other arm each bell-crank lever carries a laterally-projeeting stud1v, which comes in Contact with two stationary tappets afi .112, fixedto the tramework, by the movements oi' the bobbin-bean'is. The distancebetween the tappets encountered determines the distanec which the combis moved. The comb G on the lower beam F is moved the distance betweentwo adjacent bobbins, Whereas the upper comb on the upper bobbin-beam ismoved just twice as far.

As previously stated, the fabric is woven on this loom by sequences ofeight depressions of the treadle, eight operations being required tocomplete each point. These operations are as follows:

First opcrotiou.-'l`he lirst depression ot the treadle causes the rods ot3 and 1l to be brought into gear with the movable beam l and the beamto be raised. This elevates the upper bobbin-beam F elear above thebobbin-carriers by means of the rods (i, and the elevation of rod 1lYcauses the pile-bar U to be carried forward between the upperbobbin-beam and the bobbin-earriers to the point 415, thus leaving thepile warp-threads between the teeth of the batten above the groundwarp-thread. The foot is then taken from the treadle andthe bealn ldeseends. rlhe upper bobbin-beam, however7 remains elevated, being heldup by the levers 7 7. At the end of this operation the parts are left inthe position shown in Fig. 1 and in the diagram Fig. 17.

Second operation-Flic second depression of the treadle raises the beamB,with the rod 12 in gear. rlhis depresses the luie-threadshifting-frameC to the position shown in Fig. 1S, with the pile warp-threauls justbelow the ground warp-tlneads. \\'hen the beam l reaches the upper endof its movement, tappets strike the levers 7 7, thus releasing the upperbobbin-beam and permitting it to resume its normal position, as shown inFig. 20. XVhcn the beam descends on the release ofthe treadle, it eomesin contact with the rod 13, thus further depressing` the shittingframeC' and causing the pile warp-thretuls to be engz'iged in the lower combG.

Third operation-'Flic third depression ot the treadle raises the beamwith the rods 2, S, and El iu gear. The rods S and il cause all of thebobbin-earriers to be engaged with the upper bobbin-beam, and the rod lcauses the lower bobbin-beam to be depressed below the hobbincarriers.The descent of the lower bohbin-beam actuates the lower eomb G, movingit to the lett, (see Fig. 20,) and thus carrying the pile warp-threznlsto the left oi and crossing the ground warp-threadslVhen the ireadle isreleased, the beam l again descends, and the hooked rod 2 again raisesthe lower bobbiu-beam to its normal position and the parts are leift asshown in Fig. 21. This movement also releases the rods S and 9.

Four/Hz operation.---l`he next depression of the treadle releases therod 13, causing the shitting-frame C to resume its highest position,engaging the pile-threads with the npper comb G2 and raising their rearparts above the ground wari'J-threads. At the saine time the rods 5 5and l0 are in gear with the beam l, so that the upper bobbin-beam israised empty and the batten is shifted two places to the righi'. rlheraisingI of the bol'ibin-bealn B also Causes the comb G2 to be shiftedtwo places to the right, and as the pile warpthreads are now engaged bysaid comb they are shit'ted two places to the right, thus passing aboveand across two ground warpthreads, as indicated in Fig. The treadle isthen released, the beam li descends, and the parts resume the positionshown in Fig. 23.

Fifth operaitoit-Then the treadle is next depressed, the .rods 2, 13, 9,and 9 are in gear. The bobbins are thus suspended from the upperbobbin-liieam, the lower bobbin-beam is depressed, and theshifting-frame (2 is lowered, bringing the pile warp-threads between theteeth of the comb G. This movement carries the pile-threads down betweenthe ground warp-threads. At the same time the descent of the lowerbobbin-beam aetuates the comb G', moving it one space to thc lett, sothat the pile warp-threads are crossed beneath the ground warp-threads.This phase of the work isillustratedin Fig. 2l. On then releasing thetreadle the parts assume the po sition shown in Fig. 25, the pilewai'lrtllreads passing upward between the same ground warp-thretuls thatthey passed down between at the first movement.

These live operations complete the tyingof the pile wzup-tln'eads,th eyhavin gbeen passed around the ground warp-threzulls in the manner shownin Fig. 29. 'l'he pile-barU is then disconnected from the pilewarp-threzuls by separating from the threads the n ipping-rod o".

Sixth operation.--\Vhen the treadle is next depressed, the hooked rods1,4, 5 5, and S are in gear. Rod S causes one half of the bobbin-carriers (the even numbers) to be connected with the upperbobbin-beam, rods 5 cause the upper bobbin-beam to be raised, and rods land it cause the lower bobbin-beam, Carrying the other half of thebobbins, (the uneven numhers,) to be lowered. This separates thealternate ground warl'i-threads, as shown in Fig. 2t), and a weft-threadZ is then shot (see Fig. 31) and the treadlc is allowed to rise.

Serenth opera/.ionr-On the next de] 'u'ession of the treadle the hookedrods 1, et, 5 5, and fl are in gear. Rod i) causes the uneven-mint beredlrobbie-carriers to be connected and raised by rods 5 5 with the upperbobbinbealn, the even-numbered bobbin-earriers being lowered with thelower bobbin-beam, as shown in Fig. ,27 A seeond weft-thread Z2 (seeFig. 3l) is then shot and the ireadle lett free.

Eighth ope/'attoa.-\Vhen the treadle is depressed for the eighth andlast time, the

IOO

hooked rods 1,4, 5 5, and 8 are in gear, the same as in the sixthoperation. The bobbincarriers are separated, as shown in Fig. 28, andthe third.weft-thread Z3 is shot, (see Fig. 31,) the batten is moved onestroke, and the treadle is left free. The pile-bar U is then placedbelow the rear parts of all vthe pile warp-threads, its edge beingapplied v.to the last weft-thread. rlhe pile warp-threads are thennipped by the bar r', and a knife is passed along the groove s2, thuscutting off the threads and leaving their ends projecting the samedistance as the first ends. The pilebar U is then replaced on the drum,which is turned one space, and the loom is ready for weaving the next.point.

Each of the points of the transverse line of points thus completed hastwo tufts of the same length, and is similar to the Smyrna point, exceptthat the two tufts are raised on different sides ofthe part ofthepile-threads that lies across the two threads of the groundwarp, (secFig. 31,) whereas in the Smyrna point both tufts project up from thesame side.
